<p>
        The <span class="bold"><strong>icl</strong></span> is about sets and maps and a useful
        implementation of sets and maps using intervals. In the documentation of
        the <span class="bold"><strong>icl</strong></span> the different set and map types
        are grouped in various ways. In order to distinguish those groups we use
        a naming convention.
      </p>
<p>
        Names of concepts start with a capital letter. So <code class="computeroutput"><span class="identifier">Set</span></code>
        and <code class="computeroutput"><span class="identifier">Map</span></code> stand for the <span class="emphasis"><em>concept</em></span>
        of a set and a map as defined in the <span class="bold"><strong>icl</strong></span>.
        When we talk about <code class="computeroutput"><span class="identifier">Sets</span></code> and
        <code class="computeroutput"><span class="identifier">Maps</span></code> though, most of the
        time we do not not talk about the concepts themselves but the set of types
        that implement those concepts in the <span class="bold"><strong>icl</strong></span>.
        The main groups, <span class="emphasis"><em><span class="bold"><strong>icl containers</strong></span></em></span>
        can be divided in, are summarized in the next table:
